Octave Research OR-1 pure class A amplifier. This beast was designed by Andy Rappaport, based off of his amp-1, only with a spare no expense mentality, I think it retailed for $4000 ish in the early 80s. The entire chassis is machined aluminum! Weighs in around 70 lbs, 3 internal cooling fans, those caps... Are you ready for this? 110,000 uf x 2 per channel! utterly ridiculous. Now the fun fact, it's only 42 wpc? There are conflicting numbers between 85 and 42, 4 and 8 ohm. I believe it to be 42 @ 8 ohm, it probably specs out around 80. One sweet sounding amplifier, probably won't stay in my collection, I like power way too much. But, still a fun amp to have laying around. Enjoy these pics.
